I looked up into ncurses code from https://ftp.gnu.org/pub/gnu/ncurses/ncurses-6.2.tar.gz and https://github.com/gittup/ncurses/ to search for a wgetch definition, but it seems this function is external, where is it defined?
in that case, "extern" is a linkage modifier, a hint to the compiler about where the symbol referred to afterwards is defined (the hint is, "not here").
so the wgetch symbol usually comes in the ncurses library/shared object (libncurses.so under linux for example")

I'm fairly new to Haskell, so apologies in advance if this is a stupid question.
I'm looking for a library that can parse command line flags, but in cases where the flags aren't provided on the command line, can also obtain values from environment variables. I've tried some Google and Hackage searches, but couldn't find anything like that. Does such a library exist, or is there some other best-practice for handling such things?
Take a look at System.Environment module in Base package. Specifically getArgs and getEnv.

Is there any posix/thread related API that could help to make "a value change operation" thread-safe, without locking several statements?
Is there a posix API for Linux to do this?
GCC has atomic built-ins, __sync_val_compare_and_swap should be equivalent of InterLockedCompareExchange
If you use C++ 11, you can use std::atomic_compare_exchange_* in atomic operations library as needed.

I have a C header file with various enums and typedefs and structs defined.
Are there any awesome tools out there for turning that into a Rust file?
